IPC: C09K23/00
Filed: 1955-11-21
Abstract: An emulsifier composition comprises (1) about 50 to 90 parts by weight of a water-soluble, synthetic, non-ionic, surface-active agent containing a polyoxyalkylene chain of at least 2 alkenoxy groups and derived from an alkylphenol in which the total number of alkyl carbon atoms is from 4 to 24, and (2) about 10 to 50 parts by weight of the cyclohexylammonium salt of an alkylbenzene sulphonic acid containing at least one alkyl group of at least 3 carbon atoms.  Polyalkylene oxide derivatives of phenolic compounds which may be employed are described in U.S.A. Specifications 2,213,477 and 2,593,112.  Those preferred are the watersoluble polyalkylene oxide derivatives of alkylphenols wherein the number of alkyl carbon atoms is between 4 and 20. Exemplified alkylphenols are normal and isomeric butyl, amyl, dibutyl and diamyl phenols and cresols, tripropyl phenols and cresols, heptyl, octyl, nonyl, decyl, dodecyl, tetradecyl, cetyl, oleyl and octadecyl phenols and cresols, dihexyl and trihexyl phenols prepared from hexene-1 and phenol, diisoheptyl phenol, diocytl phenol, dinonyl phenol, dioctyl - p - cresol, di - octyl - o - cresol, didecyl phenol, didecyl-p-cresol and didodecyl phenol, and products obtained by condensing olefines obtained in petroleum refining with phenols and cresols.  The preferred cyclohexylammonium salt is the dodecyl benzene sulphonic acid salt.  The emulsifier may be used to emulsify xylene, alkylated benzenes and naphthalenes, kerosene, mineral seal oil, diesel, gas and mineral oil, textile assistants and cutting oils.  Compatible alcohols, ketones and esters and also several specified biocides may be added.  Specification 705,117 is referred to.ALSO:An emulsifier composition comprises about 50 to 90 parts by weight of a water-soluble, synthetic, non-ionic surface-active agent containing a polyoxyalkylene chain of at least 2 alkenoxy groups and derived from an alkyl phenolic compound in which the total number of alkyl carbon atoms is from 4 to 24 and about 10 to 50 parts by weight of the cyclohexylammonium salt of an alkylbenzene sulphonic acid containing at least one alkyl group of at least 3 carbon atoms.
